[osg-users] Render to texture and ClearColor
Hi i´m currently rendering to a texture using a slave camera my problem is that i can´t set the clear color to alpha. Each time the slave camera renders a new frame i get a nice blue background instead of the transparent background i´m looking for i´ve tried with values of 0.0, 0.5 add 1.0 for alpha camera-setClearMask( GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT); camera-setClearColor(osg::Vec4(0.0f,0.0f,1.0f,0.0f)); camera-setColorMask(true, true, true, true); i´ve created the texture2d attached to the camera from and osg::image with GL_RGBA and GL_UNSIGNED_BYTE formats and also i´ve tried by creating the texture2d with no parameters and setting later the texture-setInternalFormat(GL_RGBA) any idea of what i´m doing wrong??? thanks in advance _ Herramientas para combatir la crisis.

Re: [osg-users] Render to texture and ClearColor
ok, i solved it with this instruction camera-setRenderTargetImplementation(osg::Camera::FRAME_BUFFER_OBJECT); don´t know what it exactly does, but it´s working now as i want it to. An explanation of what this isntruction do will be welcome thanks Date: Thu, 24 Jul 2008 12:53:07 +0100 From: [EMAIL PROTECTED] To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Render to texture and ClearColor Dous you FBO have an alpha channel On Thu, Jul 24, 2008 at 12:42 PM, David _ [EMAIL PROTECTED] wrote: Hi i´m currently rendering to a texture using a slave camera my problem is that i can´t set the clear color to alpha.
